My DA G4 is Deceased and now my Dual Processor is on strike

2011-02-25 Thread smac0031
What a difference a day makes.

I powered down my Dual processor G4 very early this morning. When I
turned it on this morning the pilot light came on and nothing much
happened except the klorg noise. Anyway it won't boot.

Two screws, unplug everything, put it into the next to the dump
computer. Two screws, plug everything in and now its going in a 400Mhz
whatever it is with a gig of ram. If this happens again I still have
two more to the dump computers left.

When I was working with the dual processor last night it gave me some
sort of warning about bad memory. I am thinking this is why it won't
boot.


Before this happened I checked out all of my G4's. They all have
different power supplies than the DA. They each have two power plugs
on the back, and innie and an outie. The DA just has one. I am
surmising that this is one od the differences between 100 and 133 Mhz
machines.

Is it safe to say the 133mhz ram and 100mhz ram don't mix?

I have ordered almost everything I need to recover the data on the
boot drive of the DA. It was killed by a power surge not a crashed
head.

 Is it safe to say the 133mhz ram and 100mhz ram don't mix?

On a 66 MHz bus machine, you may mix PC66, PC100 and PC133 RAM in any order.

On a 100 MHz bus machine, you may mix PC100 and PC133 RAM in any order.

On a 133MHz bus machine, only PC133 RAM is permitted.

Most models do not support parity, in which case the 9th chip will be
ignored.

9/18 chip SDRAM is more for PCs than for Macs.

Most Macs expect and require so-called low density SDRAM.

That's good to know. I've got four computers in varying states  
operation. I want to go back to my Apple IIe.

First of all both HDs both Seagate Barracuda 7200 ATA Ultra's are 
dead. I tested both of them on a firewire case. When powered up and 
you hold them to your ear I can hear a very faint clicking, much 
fainter than on normal power up.

Wow!  Sounds like you took a big hit. :(

Make sure your surge protectors are still good condition, as most die 
after a few big hits.


FWIW, I'm the paranoid type.  During big storms, I shutdown my gear 
and hit the main off switch on my power strip chain.  (don't unplug - 
that leaves things ungrounded!)


I found a seller on eBay that sells circuit boards for these things. 
It looks like you need to match the
batch numbers on the big chips to my drive and have a torx 
screwdriver and you can swap out the circuit board and copy the data 
onto another drive.


Does anyone have experience with this? Is there any soldering involved?


I've done it a couple of times.  No soldering on the drives I did, 
just some tiny connectors.  YMMV (this probably varies by drive 
manufacturer).


I've used CCC to copy drives before and I have another program that 
I have used before. I don't think copying the drive will be a 
problem. The seller wants $39 for these circuit boards.


You don't have up to date backups?

currently copying my iTunes files to a drive in this dualie. This is 
slow. The dualie only has one good usb port and the keyboard is 
plugged into, so this little usb pocket drive is plugged into the 
second port on the keyboard. According to the progress bar this has 
another 13 hours to go. I started yesterday morning. It said 31 
hours when I started. I thought usb was faster than that, we are 
talking 80GB here.


Built-in USB 1.1 (12 Mbps) vs USB 2.0 (480 Mbps).

I still have 3 to the dump G4's. I was thinking about swapping out 
the power supply from one of them to test the DA to see if it is 
completely dead. I have a couple of questions. First, the DA has a 
133mhz MB and I am not sure about the other G4's, I know they came 
in both 100 and 133 flavors. Do they require different power 
supplies or are they swappable?


The GigE and DA use the same basic power supply.  Not sure what the 
other flavor G4s use.

Second, how involved is swapping the power supply?


Quite easy, actually.  Google for directions; sites like macfixit 
probably have 'em step by step.

My DA G4 is Deceased

2011-02-23 Thread smac0031
SW Michigan got hit by a snow and freezing rainstorm Sunday. My power
went out and the next afternoon when it came back on my DA G4 would do
nothing when you press the power button.

I am currently running one of my to the dump computers, a dual
processor something or other.

I was able to test several of the components from the DA in this
Dualie.

First of all both HDs both Seagate Barracuda 7200 ATA Ultra's are
dead. I tested both of them on a firewire case. When powered up and
you hold them to your ear I can hear a very faint clicking, much
fainter than on normal power up. I found a seller on eBay that sells
circuit boards for these things. It looks like you need to match the
batch numbers on the big chips to my drive and have a torx screwdriver
and you can swap out the circuit board and copy the data onto another
drive.

Does anyone have experience with this? Is there any soldering
involved? I've used CCC to copy drives before and I have another
program that I have used before. I don't think copying the drive will
be a problem. The seller wants $39 for these circuit boards.

I made a copy of each of these drive to a Seagate 500GB pocket drive
last summer. I am currently copying my iTunes files to a drive in this
dualie. This is slow. The dualie only has one good usb port and the
keyboard is plugged into, so this little usb pocket drive is plugged
into the second port on the keyboard. According to the progress bar
this has another 13 hours to go. I started yesterday morning. It said
31 hours when I started. I thought usb was faster than that, we are
talking 80GB here.

I tested the FW800/USB2.0 card in the dualie. When I did it would
power on and not boot. The dualie has a 100Mhz MB and the DA had a
133Mhz MB. I'm pretty sure this wouldn't be a problem. My conclusion
is that the FW/USB card is kaput as well.

I haven't tested the USB 2.0 hub. Seeing as how the card it was
connected to is most likely fried and my only usb ports are occupied
for the foreseeable future, whatever. I am not using my 2.0 keyboard
and I will test it with the hub. I am concerned that it might be bad.

So far, as near as I can tell the things that are definitely fried are
the power supply, the Sonnet Tempo Ultra ATA-133 card, the FW/USB card
and both HDs.

I still have 3 to the dump G4's. I was thinking about swapping out the
power supply from one of them to test the DA to see if it is
completely dead. I have a couple of questions. First, the DA has a
133mhz MB and I am not sure about the other G4's, I know they came in
both 100 and 133 flavors. Do they require different power supplies or
are they swappable?

Second, how involved is swapping the power supply?

Third, I've noticed that some of the power supplies plug into the
center and the others plug into the right side. How important is this?

Thanks,
If you want to email me off list, that's fine.
